runway-can DRAFTILIGGING.

This invention relates to improvements inv frailway car draft riggings.

The object of the invention is to provide a draft rigging for railwaycars so arranged 115l thatall the buflng and pulling strains .aretransmitted to the car under-frame at points in the rear of the gearand. adjacent the body bolster.

In the drawing forming a part of this specification, Figure 1 is a partside `elevation, part vertical, longitudinal section of a draft riggingshowing my im rovements in connection therewith. And Fig. 2 is a horifzontal, sectional view of the structure illustrated in Fig. 1, thesection being taken above the gear and below the top sill plate,

. except at the forward end where the'section 'is lower to illustratethe slots for the coupler key.

In said drawing,v 10-10 denote channel shaped, center sills spaced theusual distance apart and extending between and rigidly connected theretois`- an abutment yblock or castingv 11. The latter comprises a vertical86 front face 12, top wall 13, intermediate wall 14, bottom wall 15,vand side walls 16--16, the latter being directly riveted to the sills.In the drawing is illustrated a friction .gear

of a well known type, the same comprising 4'0 a spring cage 17 andfriction shell 18 inte- Ygrally formed, the friction shell beingeitended toward the rear. Mounted within 4the spring cage aretwinsprings 19 and withT in the Afriction 'shell are the usual frictionshoes 20, wedge 21, anti-friction rollers 22 and preliminary spring 23.rIlie wedge engages a rear follower 24 which isV resisted from `rearwardmovement by the block 11, .the rear end of a horizontal' yoke 25 beingo'linterposed between said'follow'er and said #blockThe arms of the yoke25 are slotted at their forward ends to receive a coupler Y key 26 bywhiclithe yoke is connected to a L i! draw bar 27, the latter directlyabutting the it front end'of the spring cage 17 On the top Patented Feb.4, 1919.

and bottom thereof, the combined spring cage'and friction cylinder isprovided with a substantially T-shaped slot or recess 28 in which areadapted to be seated T-shaped front ends 29 of two links-30-3Q. links 30are each provided with elongated slots 31 at their rear ends toaccommodate a vertical, heavy pin 32 which passes through alinedperforations in the walls 13, y 14 and 15 of the block 11. The links30-30 65 'are preferably reinforced, as indicated at Vthe parts areassembled. A tie plate 35 is provided to support the gear proper and`the yoke 25 is supported by means of angle irons 36-36 secured to theinner faces of the sills, said angle irons being so disposed that theirhorizontal anges are uppermost and thus forni supports for the yoke. Thepin 32 is detachably held in position by means of another tie plate 37secured to the lower flanges of the sills. The parts are assembled byfirst placin the upper link 30 in position on the spring cageandcylinder, which is done by tilting the link relatively to the cylinderand inserting the T-heads in the pocket formed under the flange 34. Thelink 30 is then swung to horizontal position. The yoke 25 is placed inposition on the supporting angles therefor, after which the friction 90cylinder and spring cage with the upper link assembled therewith, areinserted through t-lie yoke and the parts moved rearwardly so that thelink 30 will rest on the block 11. The follower 24 is then inserted 95and last the lower link 30 is applied to the cylinder. Finally, the pin32 is inserted and all the parts are lield up in place by the tie plates35 and37. The draw bar can be inserted after the other parts have beenasseinbled,as will be understood.

y In draft, it is apparent that the spring cage and friction shell willbe prevented from forward movement by the links 30 on I account of theshouldered connections between said links and the friction shell. Theyoke 25, however, moves with the draw bar and thus the .frictionmechanism`- will `be actuated through said yoke and the follower y 24.Inbuff, the yoke 25 and follower 24 11'0 The so tained, since thetendency of the center sills,

to buckle between the end sill and the body bolster is therebyminimized.

I claim: f

1. In a draft rigging, the combination With draft sills, of a frictionmechanism including a friction shell, of an abutment block mountedbet-Ween and secured to said draft sills and at the rear of the frictionmechanism, a draw" bar,x a horizontal yoke connected to said draw barand encircling the friction mechanism, a' portion of said yoke.passlngbetween the rear end of the fr1ct1on mechanism and said abutmentblock,

Geniet of this patent may be obtained for and links detachably connectedto Vsaid friction shell and to said block to prevent forward movement ofthe friction shell but permitting rearward movement of the shell.

In a draft rigging, the combination l with draft sills, of a frictionmechanism 1ncluding a friction shell, of an abutment block mountedbetween and secured to` said draft sills and at the rear of ,thelfriction mechanism, a draw bar, a yolke connected 3'5 to said draw barand encircling' the friction mechanism, and links detachably' connectedlto said friction shell and to the said block l l'to prevent forwardmovement 0f the frich n tion-shell, but permitting rearward lnove- 49ment of the shell, the yoke being arranged horizontally and said linksbeing also arranged horizontally, one above the other.

In Witness that I claim the foregoing I llave hereunto subscribed myname this 11th 45 day of July 1916.
